奇怪的变量 MySQL

Strange variables MySQL

谁能告诉我“skip_name_resolve”和“skip_grant_tables”MySQL 变量的作用?

https://dev.mysql.com/doc/refman/8.0/en/server-options.html#option_mysqld_skip-grant-tables

--skip-grant-tables causes the server not to read the grant tables in the mysql system schema, and thus to start without using the privilege system at all. This gives anyone with access to the server unrestricted access to all databases.

https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_skip_name_resolve

Whether to resolve host names when checking client connections. If this variable is OFF, mysqld resolves host names when checking client connections. If it is ON, mysqld uses only IP numbers; in this case, all Host column values in the grant tables must be IP addresses.

在这两种情况下,我都只包含了文档的摘录。按照我提供的链接阅读更多内容。
